Universal Calendar

July and August were removed because September, October, November and December were intended to be the 7th, 8th, 9th and 10th months respectively, as implied by their latin prefixes. July and August were added before September in honor of Julius Caesar and Caesar Augustus. I meant to rename January through June their latin counterparts, but I felt enough was accomplished by shifting September through December back to their rightful places. I rearranged the months in order for the vernal equinox to correspond with the new year, signifying rebirth.

Universal Calendar:
28 Days Per Month
13 Months Per Year
13 Weeks Per Quarter-Year
04 Weeks Per Month
01 Intercalary Day at End of 13th Month
01 Intercalary Day at End of 7th Month on Leap Year
